Research the aim of which was to find out stratification of main exhaust components
outside the tailpipe of the vehicle was realized in Alternative Fuels Research Laboratory of Latvia
University of Agriculture using two commercially produced testing vehicl
es (diesel and gasoline)
and exhaust gas analytical system AVL SESAM FTIR. Additionally there was created a gas
testing camera allowing to measure concentration of exhaust gas components in different heights
and windless conditions.
Regulated and unregulat
ed emissions from gasoline and diesel engines
were measured and discussed. Results obtained during the measurements showed main
stratification of toxic components from both engine types from 0.6 to 1.1
m
from the ground
making a risk to get some health pr
oblems by inhalation, especially for children. Main
components (NOx, CO, HC) of exhaust gases of gasoline engines stay in the air for about
15
minutes in height of 1.0
m
from the ground level, while methane and acetylene stay in the air
for a 15
minutes in
height of 0.6
m
from the ground level.
